  • PLATEN ROTATION DEVICE
    Publication number: 20210331286
    Abstract: A device includes a rotator assembly configured to control a rotational kinetic energy of a wafer-platen based on an electrical energy input. The device further includes a controller configured to control the rotational kinetic energy of the wafer-platen, wherein a rotational velocity of the wafer-platen is either increased or decreased. The device further includes a converter configured to generate an electrical energy output of the rotator assembly based on decreased rotational kinetic energy of the wafer-platen. The device further includes an energy storage device configured to store the electrical energy outputted by the rotator assembly based on the decreased rotational kinetic energy of the wafer-platen.

  • Platen rotation system and method
    Patent number: 10576606
    Abstract: A platen rotation apparatus includes a rotator assembly coupled with a platen. The rotator assembly operates in a first mode to increase a rotational kinetic energy of the platen based on an electrical energy input, and, in a second mode, to decrease the rotational kinetic energy of the platen and generate an electrical energy output based on the decreased rotational kinetic energy of the platen. An energy storage device electrically coupled with the rotator assembly provides the electrical energy input when the rotator assembly is in the first mode and receives the electrical energy output when the rotator assembly is in the second mode.
